thank you so much. I have a question: the power consumed by the motor is it the real or reactive power since the motor have both inductances and resistor coils?
By definition, the power consumed = I^2 R The induced current will be in the opposite direction of the current that drives the motor, but the equation still holds.
Thank you sir I have a question please I have a motor nameplate, the information given : I = 27.13 A V = 415 V Output power = 15 kw And p.f is 0.87 When i used the method which you have explain i got 0.76 p.f and it does not matching p.f which is given ( 0.87) 😅
Thank you so much for the video! Keep making us smarter!
Professor, isn't it the unit of apparent power : Volt-ampere (VA) and not Watts (W)... I think you made an oblivious mistake there.
Technically you are correct.

It is my trusty companion.
I'd recommend one small correction. You used Watts as the unit for Apparent Power (S). This would typically use VA for the units.
You are correct. Thank you for the input.
How can i calculate the reading of the input power given the output power, power factor, efficiency and voltage of 3 phase
Does the line current is the full load current amp of the motor?

Thank you and welcome to the channel!
Thank you prof
You are welcome
Thank you sir
I have a question please
I have a motor nameplate, the information given :
I = 27.13 A
V = 415 V
Output power = 15 kw
And p.f is 0.87

The power factor does depend on the load and the power consumed (I^2 R) versus the power provided (IV).
Thank you very much teacher.
Amazing
Thank you. Glad you found our videos. 🙂
I don't think that ".2" is a significant digit.
thank youu
You're welcome!
Great
